In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?
There is an elevated number of immature thrombocytes.
There is an elevated number of immature neutrophils (bands),
There is an elevated number of mature neutrophils (segs)
There is an elevated number of mature erythrocytes
The Correct Answer is B
A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.
B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.
C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.
D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.

Correct Answer is A
Explanation
A. "Eating a high fiber diet will reduce my risk for developing skin cancer." There is no evidence that a high-fiber diet specifically reduces the risk of skin cancer. This statement indicates a misunderstanding and a need for further teaching.
B. "I should check my skin monthly for any changes." Regular self-examinations are recommended to detect early signs of skin cancer.
C. "I should use sunscreen even on cloudy days." UV rays can penetrate clouds, so using sunscreen on cloudy days is an important preventive measure.
D. "I should avoid the use of tanning booths." Tanning booths increase the risk of skin cancer, so avoiding them is a correct preventive action.
Correct Answer is A
Explanation
A. 1 cup canned black beans - Black beans are high in iron and an excellent dietary recommendation for someone with iron deficiency anemia.
B. 8 oz whole milk - While nutritious, milk is not a significant source of iron and can actually inhibit iron absorption due to its calcium content.
C. 1.5 oz raisins - Raisins do contain some iron, but the amount is relatively small compared to black beans. They are a good supplement but not the best primary source of iron.
D. 8 oz black tea - Tea contains tannins that can inhibit iron absorption, making it an unsuitable recommendation for someone needing to increase their iron levels.
